KINGSTON, Jamaica (AP) — Usain Bolt overcame a glacial start to win his 100-meter semifinal Friday night in the Jamaican Olympic trials, finishing in 10.01 seconds to set up a showdown in the final against Yohan Blake and Asafa Powell.

Bolt was in sixth place with about 40 meters left but overcame the deficit and jogged through the finish line to beat Michael Frater by 0.01 seconds.

Powell won his semifinal heat in 9.92, 0.03 ahead of Nesta Carter, with Blake another 0.01 back.

All the top women advanced — Shelly-Ann Fraser-Pryce, Veronica Campbell-Brown, Sherone Simpson and Kerron Stewart. Stewart flinched in the starting block and the gun went off, but officials allowed her to stay in the race.

The finals were scheduled for later Friday.
